The development of a highly efficient two-step process for the manufacture of the α2δ-ligand imagabalin hydrochloride 1 is described in 50% overall yield from (R)-3-methylhexanoic acid 2. Key aspects of this route include the development of a one-pot process for the synthesis of β-enamine ester 7 and its subsequent diastereoselective hydrogenation with a Ru-(S)-BINAP catalyst. The use of a combination
